Bending a ping-pong racket
This case is pretty basic modeling stuff, so I will not go deeper in simple details and just show you an overview not to write full blown tutorial here (it's not place for this). If this is your first day you will need to know some starter pack things like:


Edge Loops and Edge Flow in general (tris, quads, ngons, poles and such),
creating, joining, cutting (Loop Cuts), extruding faces,
adding simple modifiers (Mirror, Subdivision Surface, Curve).


Everything is here, on Blender Stack Exchange as well as on YouTube or any other place with Blender resources (there is topic with them here too).


  I'm trying here some new answer technique, so be gentle. I'll expand
  this answer as much as OP will need it.


Overview:




Start with simple Plane at extrude one edge along green curve 9 times (to get 10 faces).
Add Mirror Modifier with Clipping checked.
Fill in faces in the middle of paddle (I don't know how this rubber surface is called).
Extrude bottom face to have a handle.
Add Subdivision Surface Modifier.
Select all and extrude it to gave depth to paddle.
Add Loop Cuts along green curve (the same from first step) and the short one at the bottom.
Add Bezier Curve.
Add Curve modifier for paddle. Important! It should be above Subdivision Surface.
Move the paddle along Curve to adjust it.
Edit Curve to give it bend.


In the blend file, on layer 2 you have 3 models of paddle to study them.
